The Jetting

Availabe size:
Pilotjet: #32.5 #35 #37.5 #42
Mainjet: #110 #138 #150 #155 #160

Currently on PJ #37.5 MJ #160 Needle at middle clip, 2 turn.
Default setting for the air screw is 1 turn out, max turn at 1 ¼, 1 ½ turn.

Notes:

• Warm up your engine to the proper operating temperature. 
• Turn the idle up so it is idling about 500 RPM’s higher than normal.
• Turn the airscrew all the way in until it bottoms out, once bottomed out slowly back the screw out a ¼ turn at a time (give the engine 10-15 seconds between each ¼ turn of the screw, to allow the engine to catch up w ith the adjustments).
• Continue backing the airscrew out until the engine idles at its highest RPM.
• The preferred setting window is between 1 and 2 turns.
• If the engine idles at its highest RP M from 0-1 turns out this mean s the pilot setting is on the Lean side and a larger pilot jet should be installed.
• If the engine idles at its highest RPM at over 2 turns out, this means the pilot setting is on the Rich side and a smaller pilot jet should be installed.
